Hi,
My cousin has recently purchased this mobile from amazon, he is very much satisfied with the performance of the mobile as its is performing like a charm he was telling that there was no lag what soever and the battery life of the mobile was awesome it lasted him more than a full working day with heavy usage this is because of the three gigabytes of ram present in the mobile and the gaming performance was awesome as I worked every game you threw at it without any lag overall both of us are very much satisfied with the device and would highly recommend it to everyone, thank you.
